Anyone choose to have just one child?

We only have 1 right now...and as you can tell by my signature, it's not for lack of trying to have a 2nd.I desperately want a 2nd, DH it depends on the day, honestly. He's so burned by the failed placement and failed relative adoption from this past year he's happy as a family of 3 for now. I hate the idea of S being an only. I have cousins who were only children who hated it, even though we all come from a huge family and all us cousins played together every weekend. We live several states away from my family so S doesn't have the cousins to play with all the time, and DH's family doesn't really have little ones for her to play with nearby either. So long story short, we are a family of 3 for now, hoping to have another but don't know if/when it will happen for financial & emotional reasons.
